Title: Rotary ram collet lock needle point guard
Inventor: BRIMHALL GREG L
IPC: A61M5/32
Filed: 1996-06-26
Abstract: A needle point guard having a movable collet to lock the needle in place in the shielded position is provided.  The needle point guard of this invention includes a housing, a collet, a rotary ram, a threaded cam fixed to the rotary ram, a spring disposed between the rotary ram and the housing and a trigger catch to hold the threaded cam in place against the force of the spring.  The spring is wound when the needle is in the unshielded position.  When the needle is withdrawn into the needle point guard, the trigger catch pivots to allow the spring to rotate the threaded cam.  This rotation is translated into axial motion by the treads on the threaded cam and threads formed on the inside of the housing.  This axial motion forces an annular flange on the collet to bite down on the needle, to thus hold the needle in place in the shielded position.

Title: Subscriber identity authentication in fixed cellular terminals
Inventor: GARCIA AGUILERA JOSE MARIA
IPC: H04W84/14
Filed: 1995-12-21
Abstract: The fixed cellular terminals (TCF) include a subscriber identity module which, in order to permit authentication of the identity of the subscriber (U) without any intervention on his part, is fixed. It is of particular application in fixed cellular terminals (TCF) of the GSM type that form part of an access network based on the infrastructure of a cellular mobile network. These subscriber identity modules incorporate the function of subscriber identification number verification. During the installation stage each fixed cellular terminal (TCF) stores the subscriber identification number, which it later provides to the subscriber identity module making it become fully active when the number supplied coincides with that held in the subscriber identity module. In the initialisation process, the fixed cellular terminal (TCF) generates a new subscriber identification number, that it stores internally in its subscriber identity module for use in subsequent reinitialisations.

Patent CA-2216691-A1 (CA)
Inventor: JASINSKI FELIKS
IPC: B25C1/02
Filed: 1997-11-19
Abstract: This invention is a manually operated tool for driving nails, which securely holds the nail to be driven in the central tube of a nozzle at the front of this tool, by means of a magnet. Force is applied to the head of the nail by means of a striker, securely attached to a striker housing which slides back and forth inside a guide tube, and forces the nail out of the nozzle. The movement of the striker assembly is controlled by the operator pushing and pulling on the hand grip which transmits this motion directly to the striker housing via the inside front face of the end cover grip which is screwed into and thus an integral part of the hand grip. The operator first pulls the hand grip to the full extent of the guide housing until it is stopped by the retainer, then holds the nozzle against the surface into which the nail is to be driven with one hand and operates the hand grip which activates the striker with a sliding movement of the other hand, in a manner similar to the operation of a hand-held bicycle tire air pump, thus driving the nail into the surface. With the tool in a horizontal position, nails of various sizes can be pre-loaded into the nail magazine through a slot in the nail magazine cover. By releasing the safety catch, the spring in the guide housing pushes back the hand grip ready for the nail to be indexed into the nozzle. When a compartment in the nail magazine comes into line with the opening in the nozzle housing, the nail in the magazine compartment will drop through the opening into the central tube of the nozzle where it is held by a magnet until forced out by the striker. Nails may also be loaded into the nozzle manually from the front end by sliding the head of the nail in first where it will be held by the magnet until it is forced out by the striker. On completion of the job and for storing purposes, the hand grip is pushed forward and secured with a safety catch, thus keeping the nozzle empty.

Abstract: A pipe connection, device comprising a reentrant groove near the end of the pipe and pressure projections which bear on the outer surface of a narrow inner rind so as to force the end of the ring into the reentrant groove leakage and greater structural strength to tension on the pipe. The reentrant groove is positioned to be exactly within the end of the ductile ring within the connection device. The tightening nut on the pipe connection device also has pressure projections on the inner surface bearing against the outside of the ductile rind. This reduces friction on the pipe and thus allows easier tightening and greater pressure to be applied to force a salient of the ductile ring into the reentrant groove.  ~ Alternative embodiments disclose pressure projections on the ductile rind, a two pan ductile ring, and a ductile ring capable of reducing its circumference as it is tightened. Also disclosed are devices for making the reentrant groove near the end of the pipe.
